SYNOPSIS

       jcat [-f fstype ] [-vV] [-i imgtype] [-o imgoffset] [-b dev_sector_size] image [images] ] [ inode ] jblk

DESCRIPTION

       jcat  shows the contents of a journal block in the file system journal.	The inode address of the journal can be given or the default loca-
       tion will be used.  Note that the block address is a journal block address and not a file system block.	The raw output is given to STDOUT.

ARGUMENTS

       -f fstype

       -i imgtype
	      Identify the type of image file, such as raw or split.  Use '-i list' to list the supported types. If not given, autodetection meth-
	      ods are used.

       -o imgoffset
	      The sector offset where the file system starts in the image.

       -b dev_sector_size
	      The  size,  in  bytes,  of  the  underlying  device  sectors.  If not given, the value in the image format is used (if it exists) or
	      512-bytes is assumed.

       -V     Display version

       -v     verbose output

       image [images]
	      One (or more if split) disk or partition images whose format is given with '-i'.

       [inode]
	      The inode where the file system journal can be found.

       jblk   The journal block to display.
